Description:

A battery management system (BMS) monitors the status of batteries, controls their charging and discharging processes, and performs other functions. The HX-2S-D20 charge-discharge controller module can connect two 18650 batteries at the same time. It has short circuit, overcharge, and over-discharge protection. It also cuts off the power supply to the batteries when at least one of them reaches full capacity. This BMS controller can operate for more than 30,000 hours and has a maximum current of 20 A.

The HX-2S-D20 BMS module has 5 pins:B      : Battery positive pole
B-      : Battery negative pole
BM    : Mid-point of a battery assembly
P-      : Negative charge / discharge terminal
P      :Positive charge/discharge terminal

If the maximum permissible value of the supply voltage is exceeded, the charge controller activates the “protection” mode. In order to restore the module, it is necessary to re-apply voltage to the input of the BMS board or wait a while until the charge controller automatically disables protection.

Power is supplied to the module from an external power source. The voltage range of the module is from 7.4 to 8.4 V. For charging, you can use a step-up voltage converter with a current limiter. Please note that this module is not a charger.

  1. Small size designed for a four-cell battery pack.
